SELVAGE -GUIDE FOR CLOTH-SHEARING MACHINES SPECIFICATION forming part ofLetters Patent No. 598,264, dated February 1, 1898.

Application-filed July 9,1897. Serial No. 643.960. (No model.)

dence and State of Rhode Island, have invented a new and usefulImprovement in Sel vage-Guides for Cloth-Shearing Machines; andI herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming partof this specification. This invention has reference to an improvement inthe class of cloth-shearing machines in which a series of verticalparallel sections operated by a sliding bar with a cam-slot formedtherein are used, as is shown and described in United States Patent No.207,091, of August 13, 1878, to Amasa VVoolson, for improvement in restsforcloth-shearing machines. In these machines the rest is operated toadjust itself to the width of the cloth to be sheared by the serratedfeelers over which the selvage passes. As the selvage is usually more orless wrinkled, it is found in practice that the selvage will pass overthe serrated feelers for some distance without affecting the feelers.

The object of this invention is to hold the cloth at all times againstthe serrated feelers and insure the automatic adjustment of the rest;and to this end the invention consists in providing the sliding bar ofthe rest with an arm extending longitudinally above the sliding bar,provided at its end with a bracket on which a selvage-guideis supported,whereby the cloth is held in contact with the serrated feelers, as willbe more fully set forth hereinafter.

Figure 1 is a front View of the automatically-adjustable rest, showingthe same provided with the improved selvage-guide. Fig. 2 is atransverse sectional view of the rest, showing the selvage-guide. Fig. 8is a sectional view of the end of the selvage-guide. Fig. 4 is a topview of a modified form of the selvage-guide.

larged scale, of the selvage-guide and the arm supporting the same.

In'the drawings, A A indicate the sliding sections of the rest, whichare controlled by the slot 13, formed in the slide 0.

D is the backing or support; E, a bracket secured to the slide 0 andforming the piv Fig. 5 is a top view, on an en- 1 otal support for theserrated feeler G and the cam H; F, a double ratchet-bar in connectionwith the feeler G and the cam H.

The drawings show only one end of the rest; but in practice both ends ofthe cloth-rest of a shearing-machine are constructed in the same way,with the positions of the parts'reversed.

The double ratchet-barsFpn opposite ends, are operated to reciprocate,and when oneor the other side of the cams I-I engage with theratchet-bars F the slide 0 is moved, and this operates the sections A,as is more fully de scribed in the Patent No. 207,091 to A. Wool son,before referred to.

To the slide 0, or to an extension 0 of the slide, I secure the arm K,the base K of which is provided with two elongated holes, so that it canbe adjustably secured to the slide 0 or the extension 0. The arm K isbent or offset, so as to extend above the cloth-guide and permit thecloth to pass under the arm. To the free end of the arm K the bracket Kis secured, and this bracket K may be bent to form the guide-finger Kthe end of which is bent upward to insure the entrance of the cloth atall times under the guide. In the preferred form I use a separateguide-finger K having the conical shoulder K and the roller or loosecollar K and secure the same to the bracket K by the nut K which nut maybe secured against getting loose by vibration in the usual manner. ThebracketK is secured to the arm K by the nut K or a screw tapped into thearm and provided with a head, so that the bracket may be adjusted tobring the guide-finger or the roller K in contact with cloth of varyingthickness and hold the cloth, the selvage, or the list, as the selvageof woolen cloth is termed, in contact with the feelers G at the oppositeends of the rest, and thereby secure the prompt operation of theautomatic rest and the clean shearing of the cloth through the wholelength of the cloth.

Having thus described my invention, I claim as new and desire to secureby Letters Patentv 1. In a cloth-shearing machine, the combination withthe cloth-rest,v the sliding end sections of the rest, the slideoperating the end sections, and the feelers controlling the position ofthe slides, of guide-fingers Snip ported on the slides, said fingersbearing on the cloth at the point of contact with the feelers, wherebythe prompt adjustment of the cloth-rest is secured, as described.

2. In combination with the cloth-rest, the sliding end sections, theslide operating the end sections, and the feelers controlling theposition of the slides, of an arm adjustably secured to the slideoperating the end sections at a point beyondthe possible passage of thecloth, and a finger-bracket supported by the arm, said finger bearing onthe cloth at the point of contact with the feelers, as described.

In witness whereof I have hereunto set my hand.
